Abstract
The present disclosure is related to display panels, especially to flexible electronic devices. By means of adding an inorganic membrane with surface roughness between a bonding layer and a PI film, in order to effectively improve the dimensional stability of plastic substrate and the water/oxygen barrier property of flexible substrate during the PI film fabrication and the follow-up process, improving the yield of good products and prolonging the working life thereof.
